Critical Elements Reports High Grade Lithium, Tantalum and Cesium in The Last Holes of The Winter Drill Program
Critical Elements Confirms Rose West Expansion as Drill Program Concludes

Executive Summary
- The most recent release (May 21, 2026) reports final assay results from the Phase 1 Winter 2026 drill program at the Rose West Discovery.
- Drilling expanded the mineralized footprint from 450 m x 370 m to 1,250 m x 800 m.
- New spodumene-bearing pegmatitic bodies identified (Pegmatite 5) in the southern portion of the Main Target Area.
- Significant intercepts confirmed high-grade Lithium (Li2O) and Tantalum (Ta2O5) with lateral continuity, including holes RW-26-38 to RW-26-43.
- Cesium oxide (Cs2O) grades appear to increase towards the south, with spikes near 1,000 ppm in recent holes.
- Preparation is underway for a follow-up Summer 2026 Drilling Program.
- Historical context shows this program was announced in February 2026 and results were progressively released in April and May (May 4, Apr 29).
- A separate news item from May 19, 2026 regarding Power Metallic Mines Inc. (Saudi Arabia JV) is noted but distinct from Critical Elements' core asset base.
Material Impact
- The news confirms expectations set in previous releases (Feb 3, Apr 1, Apr 29, May 4) regarding the expansion of the Rose West footprint.
- While the grade continuity and thicknesses (10 to 40 m) are positive, they were largely anticipated based on the predictive geological model mentioned in earlier updates.
- The identification of Pegmatite 5 adds volume but does not represent a fundamentally new discovery outside the known corridor.
- No new financing or strategic investor announcements accompany this release; capital needs remain funded by previous C$7M raised in Dec 2025.
- The market impact is likely muted as the information was progressively disclosed over the last three months, making it incremental rather than a surprise catalyst.
